^{note (1) in page 39} It may seem surprising that the table does not show a fall in unit non-wage factor costs in the last period. That it does not is due to the fact that this item includes not only gross trading profits (which did in fact fall—gross, as well as per unit of output in this period) but also rent and self- employment incomes (which rose) as well as the surpluses of public corporations and enterprises. That the rise due to indirect taxes is so much larger in 1968/9 than in 1967/8 (it might have been expected to be about the same) is due to the literal accounting nature of the exercise. If SET is account ed for on an ‘accrual’ rather than on a payments basis, which is how it is treated in the national accounts, this discrepancy would be ironed out. Presumably, in practice, firms will tend to have based their prices on an accruals-based concept of SET, so that variations in profit margins absorb some of the temporary rises and falls in recorded net indirect taxes.

^{note (2) in page 39} The previous tendency for export prices to rise less than domestic prices had, however, never applied to the United Kingdom with quite the same force as to the generality of overseas industrial nations. See National Institute Economic Review no. 43, February 1968, page 23.

Bowers, P. C. Cheshire and A. E. Webb, ‘The change in the relationship between unemployment and earnings increases’.

^{note (1) in page 41} This follows the investigation by Bowers, Cheshire and Webb (op. cit) which indicated that since 1966 and until 1969 vacancies continued to give a reasonable fit in equations of this type, where unemployment did not.

^{note (4) in page 42} Seasonal and ‘incomes policy’ dummies failed to perform well and were omitted from the regressions quoted in table 4. Central difference expressions of the rate of change were used.

^{note (5) in page 42} An additional argument for doing this would be that it is now apparent that, relative to unemployment, vacancies suggest a much more buoyant labour market in 1967, 1968, and 1969, and some of the assessments of incomes policy used unemployment-related equations to check policy effectiveness. These equations would presumably have tended to give rather low predicted figures of the rate of wage and earnings increase in the absence of incomes policy, leading to unduly low estimates of policy effects. But, for what it is worth, the earnings/vacancies relationships quoted in table 3 above do not show a significant effect when incomes policy ‘dummies' are used, and the estimated effect, even taken at face value, is extremely small.

^{note (1) in page 44} The estimates were obtained by subtracting from the value of expenditure at current market prices the net indirect taxation as given for each group in the Blue Book. The resultant current price estimates were then deflated by the constant (1963) price estimate to obtain the deflators. As the constant price estimates were only available at market prices, the procedure involves assuming that the average rates of net indirect taxation for each group in 1963 remained constant throughout.

^{note (2) in page 44} This in turn implies that the relative apportionment of expenditure on different goods and services remains unchanged at the zero overall rate of price inflation.

^{note (1) in page 48} ‘Redistribution’ is implicity defined here as a narrowing of differentials in percentage terms. Redistribution of this kind is, of course, quite compatible with a widening of differentials in absolute terms.

^{note (2) in page 48} Comparison of income shares within the corporate sector might have been preferable, but 1970 data on this basis were not available. The annual data for 1959-69 show, however, that the trends and year-to-year movements in corporate income shares are very similar to those in total income shares shown in the table.

^{note (1) in page 49} Deviations of the profits share from its trend were regressed on deviations from trend GDP and the 1969 and 1970 observations were then predicted from the equation. The results suggested the order of magnitude referred to in the text.
